WINDOW-PANE CLASP.

SPECIFICATION forming part of Letters Patent No. 576,360, dated February2, 1897. Application filed September 2, 1896. Serial No. 604,641. (Nomodel.)

To all whom t may concern:

Be it known that I, JOHN F. BOWMAN, a citizen of the United States,residing at Lakeville, in the county of Plymouth and State ofMassachusetts, have invented certain new and 'useful Improvements inIVindow-Pane Clasps; and I dohereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. i

This invention relates'to certain new and useful improvements in meansfor securing and holding glass in window-sash and it has for its object,among others, to provide a simple and cheap device by which the glassmay be quickly and easily held in the sash and which can be readilyremoved for the insertion of a new glass when one becomes broken.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon form a part of thisspecification, and in which-- Figure l is a perspective view of myimproved glass-securer. Fig. 2 is a view of a window-sash, showing theglass held in position by my improvement. Fig. 3 is a crosssectionthrough the sash.

Like letters of reference indicate like parts throughout the severalviews.

Referringnow to the details of the drawings by letter, A designates theframe, which consists of the sidebars @,of steel or other material,provided with the sharp points or projections or spurs a. The bars areabout one-half an inch wide, and the number of points may be varied asmay be found most expedient. The bars should be of a length inaccordance with the length of the glass'which the frame is designed tosecure. The double-end bars B of the frame are pivotally connected withthe ends of the bars a and jointed at their adjacent ends, as at b, andthese end bars are also provided with the projections or sharp points orspurs B', similar to those on the bars a.

By lthe term jointed I mean pivote-d,

hinged, or otherwise joined or connected so as to have movement withrelation to each other, as upon a pivot.

In practice the glass is placed in position in the sash D, which isformed with a rabbet for the glass to be put against from the insideinstead of the outside, as heretofore. The rabbet is beveled on theoutside, as if the putty were there. The frame is then placed upon theglass and-the end bars pushed upon to straighten them, when the spurs ofthe end and side bars will embed themselves in the wood of the sash andsecurely hold the glass. In case a pane of glass is broken it can beeasily removed by removing the frame, placing the new glass in place,and then applying the frame, as before. The frame can be painted tomatch the color of the paint on the sash.

Modifications in detail may be resorted to vention or sacrificing any ofits advantages.

l. A frame for the purpose described. consisting of the side barsprovided with spurs, and the jointed end bars connected thereto andprovided with spurs, substantially as and for the purpose specified.

2. A frame for the purpose described consisting of side bars havingpermanently-af-4 fixed spurs projecting laterally therefrom, and endbars provided with spurs extending laterally therefrom, each end barcomprising a number of sections joined together and pivotally connectedto the ends of the side bars, substantially as described.

3. A frame for the purpose described having side bars and means forconnecting the ends thereof for spreading said bars and retaining theglass in position, substantially as described. y

4. A frame for the purpose described comprisin g side bars with spursand end portions, having spurs, and pivotally connected to the sidebars, and composed ol"y pivotally-united sections, substantially asdescribed.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
